摘要
提出了一种适用于紫外光固化的新型光源系统。该系统以大功率紫外光LED和光学系统组成阵列结构来实现固化光源的高辐照度,大功率LED阵列由多路可控恒流源系统控制,根据固化材料的特点外部设定驱动电流,控制光源发光强度。与常用的高压汞灯相比,该系统无需高压驱动和冷却设备,具有操作简单、固化效率高和绿色无污染等优点。实验结果表明,该系统能够发出均匀稳定的高强度紫外光。
A novel light source system for low curing is presented. High power LEDs and optical systems are arranged as ar rays in order to realize high radiation intensity of this UV curing source. High power LED arrays are controlled by multipath controllable consmat current source,and the light source＇s output is set up based on the driving current under the characteristics of the UV cured material. Compared with high-pressure mercury lamp used in industry,this UV curing source dispenses with high-pressure driving and cooling equipments,and has several advantages such as simple operation,high curing efficiency,green without pollution. The experiment results show that even,stable and high-intensity UV radiation can be available with this new system which has wide application foreground.
